F1: MitreTechniqueTag inline classes replaced with className="tag-mitre gap-xxs"
(index.css .tag-mitre is now the single source of truth for technique tags).
F2: boxShadow block removed from tailwind.config.ts — no component referenced
shadow-soft-lift / shadow-floating / *-dark; DESIGN.md §Don'ts prohibits shadows.
F4: StatusBadge.test.tsx gains 3 class assertions (bg-warn-soft / bg-primary-soft / bg-cloud)
mirroring SimulationStatusBadge.test.tsx pattern. Test count: 136 → 139.
